  • GREENGUARD Gold Certified

Our conversion kit makes it easy to transform the expertly built Marlow Crib into a furniture piece of lasting use and comfort as your child grows. With straight lines and gently tapered feet, it takes its cues from midcentury design.


  • Built from solid pine and iron.
  • All wood is kiln dried for added strength and lasting beauty.
  • Multistep finish is sealed with a protective, child-safe lacquer for extra durability.
  • GREENGUARD Gold Certified. Meets or exceeds stringent chemical emissions standards.


  • Easily adapts from crib to cozy toddler bed.
  • When purchasing a crib, it is strongly recommended to purchase the toddler bed conversion kit at the same time.


  • Use only a fitted bottom sheet that is specifically made for crib use (Pottery Barn Kids fitted crib sheets have elastic around the top and bottom, rather than around the entire edge, for added safety), along with a mattress pad and/or a waterproof pad.
  • If you use a blanket, ensure it is tucked around the sides of the crib mattress and covers your baby only up to the chest.
  • Do not place decorative pillows, quilts, comforters, sheepskins or stuffed animals in the crib while your baby is sleeping, as they may prevent proper air circulation around your baby’s face.
  • When your child is able to pull up to a standing position, you should remove the crib bumper.
  • Do not place cribs next to a window, near cords or under heavy objects that could fall into the crib.


  • All Pottery Barn Kids juvenile products are tested at 3rd party CPSC accredited labs to meet or exceed all industry voluntarily and regulatory safety requirements.


Locate your crib’s SKU number: You’ll find that all of our cribs have a Tyvek envelope located on the metal base of your crib. The PO and SKU number will be located on stickered label on the bottom left corner of the envelope.

    Our Safety and Quality Commitment

    Our Commitment

    At Pottery Barn Kids, we have a firm commitment to safety and quality. We take great pride in our timeless designs, sustainable sourcing, premium materials and expert craftsmanship.

    Lead Testing

    One of the most important tests for developing infants and children. We require extensive lead testing at both surface and substrate levels to ensure that our products exceed both those levels achieving higher than industry standards in many countries.

    Anti-Tip Testing

    We test our furniture to prevent tip over hazards, testing above the required standards. In addition we provide anti-tip kits with all our furniture for added protection. We also put our anti-tip kits through multiple tests to ensure they will safely support and secure your new furniture in your home.

    Global Safety Standards Acumen

    Since quality and safety standards can change from place to place, we aggregate the highest safety standards from the many countries and nations we do business with to holistically develop our own global standards for our many products. Our quality teams attend regular ASTM meetings and conferences to stay ahead of industry trends.

    Thinking as Designers and Engineers First

    We design safety requirements into our products like no sharp edges & points, small parts, finger or head entrapment hazards as a foundation for our furniture and other products. We source high-quality materials and substrates in our products especially for our loft and bunk bed furniture so your children can sleep safely.

    3rd Party CPSC-Nominated Testing Partners

    We stand by each product and test in our name for accountability. We use accredited 3rd party labs nominated and regulated by the CPSC (Consumer Product Safety Commission). Our partners test everything in the box, including labels, packaging and materials to ensure product safety compliance.

    Your Opinion Matters

    We review all returns and take customer feedback very seriously. Many of us at Pottery Barn Kids are parents ourselves and listen to your feedback to make better and safer products for healthier homes.
